Worldwide Oversleep
世界中の目覚まし遅らせちゃうぞ
Worldwide Oversleep is a Battle Cats stage in #04 Mischievous Schemes. It costs 100 energy and sends 13 enemy spawn lines — led by Dark Emperor Nyandam as the boss — against a 150,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Red and Floating traits, so cats that target them do the most work here.
